Internal Gear Pumps - PDL

ISO logo

ISO 9001:2015 Certified

Sealless, sealed, or packed box PDL Series gear pumps are avilable for a wide range of applications in several material and diver configurations (see the separate PDS models for smaller pumps, including fractional sizes).

Magnatex® PDL Series

Positive displacement pumps for a wide range of applications in several material and driver configurations. (See separate PDS Series literature for smaller pump models, including fractional-sizes.)

  • Ideal for high-viscosity liquids
  • Used in process found in the chemical, Petrochemical, refining and other industrial markets as well as OEM’s
  • Available in cast iron, steel and stainless steel materials;internal component materials selected by application
  • Robust, modern design with standard 180° inlet/outlet configuration; 90° suction/discharge configuration available
  • Mechanically sealed (single, double and cartridge), packed box, and sealless, magnetically driven models available as appropriate for the application requirements or customer preference
  • Suitable for direct or gear reducer drives, long- or close-coupled
  • API 676 2nd edition compliant with limited comments
  • Front and rear jackets for fluid heating or cooling available; electric heating optional
  • Self-priming capable to the limitations of the application
  • ntegral, bypass relief valve available and recommended
  • Bi-directional pumping by changing motor rotation and relief valve orientation
  • Convenient clearance adjustment
  • Easy access to internal components from either side for maintenance when required
  • Back pull-out design for long-coupled pumps with spacer coupling allows ease of maintenance when needed
  • Both horizontal and vertical mounting (with special provisions and proper location in the system)

Pump Dimensions

PDL Series pumps are available in a number of configurations including long-coupled to a direct-drive motor, long-coupled to a reducing gear or gear motor, or close-coupled to reducing gear drive, as well as close-coupled, direct drive. Specific dimensional drawings will be provided for individual proposals similar to the illustration below:
